Testing a school-based program to promote digital health literacy and healthy lifestyle behaviours in intermediate elementary students: The Learning for Life program.

ABSTRACT

Promoting digital health literacy and healthy lifestyle behaviours in children can lead to positive long-term health outcomes and prevent chronic diseases. However, there are few school-based interventions promoting this education to intermediate elementary students. The objective of this study was to test the effectiveness of a novel intervention to increase students' digital health literacy and health knowledge. Learning for Life is a classroom-based education program, developed for grade 4-7 students and delivered by teachers over six weeks. Three Canadian schools were recruited to deliver the intervention in 2018. This study had a pre-post design and no control group. Students' self-reported digital health literacy and healthy lifestyle behaviours were measured at pre-intervention (n = 126), post-intervention (n = 119), and two-month follow-up (n = 104). Students at pre-intervention had a mean (SD) age of 10.98 (0.56) years (57.1% females). Almost all (97%) students had unsupervised access to the Internet through a computer or smartphone. From pre- to post-intervention, students' digital health literacy increased (p = 0.009), but decreased from post-intervention to follow-up (p < 0.001). Post-intervention, the majority of students could identify at least one healthy behaviour (e.g., exercising one hour/day) and reported making at least one healthy change in their lives (e.g., eating more fruits/vegetables). This study demonstrated that the Learning for Life intervention can improve intermediate elementary students' digital health literacy over the short-term and help them learn and retain healthy lifestyle knowledge and behaviours. These findings affirm the need for interventions promoting digital healthy literacy and healthy lifestyle behaviours for this age group.
